This penis replacement team should join Dr. Atala and get the replacement members from people’s own stem cells:

“Dr. Anthony Atala, a urological surgeon and professor of regenerative medicine at the Wake Forest Institute for Regenerative Medicine in North Carolina, has developed a method uses the patient’s own phallic cells to make a new penis.

“The phallus is actually much longer than you think,” he explained to The Guardian. “It goes all the way behind the pelvis, so no matter the extent of the damage, there is a high probability that there are salvageable cells.” …

Atala says organ regeneration is necessary as fewer organs are harvested for donation. He has had success with engineered bladders and vaginas, but the penis’s structure proved complex — until he thought to scrub a donor penis of its donor cells.

“You’re left with a mostly collagen scaffold — a skeleton if you like, that looks and feels just like the organ,” James Yoo, one of Atala’s collaborators at the institute, explained to The Guardian. “Think of it like a building. If you remove all the furniture and the people, you’re still left with the main structure of the building. Then you replace the tenants with new ones. That’s the whole idea. It’s just that the building is a penis and the tenants are cells.”

Atala can then insert the patient’s own cells and transplant it.

So far, he’s made six lab penises and is awaiting approval from the U.S. Food and Drug Administration so his team can begin implanting them. It should be within the next five years, he said. But first they imagine doing partial transplants — making smaller portions of the penis to help men with erectile dysfunction. …
